SNAP-FASTENER.

Specification of Letters Patent.

Patented Nov. 30, 1920.

Application filed September 5, 1914. Serial No. 860,379.

To all whom it may concern:

Be it known that I, ELIZABETH J. SMITH, a citizen of the United States of America, residing in Larchmont, in the county of Nestchester and State of New York, have invented certain new and useful Improvements in vt-tuapJFasteners, of which the fol.- lowing is a specification.

This invention relates to snap fasteners, and aims to provide improvements therein.

By the present invention, a simple, cheaply and readily manufactured, and eflicient snap fastener is produced.

An embodiment of the snap fastener is illustrated in the accompanying drawings, wherein- Figure 1 shows a top plan view of a snap fastener in which the spring is applied, and

Fig. 2 is a vertical section of t] e parts shown in Fig. 1;

Fig. 3 shows a spring embodying the invention.

Referring to the drawings, numeral 1 designates a socket member of a snap fastener preferably formed of sheet metal, and 2 a bent spring of any suitable contour. The socket member is preferably provided with a socket 3 with slots f in the sides thereof through which portions of the spring are adapted to project for engaging a ball-mom her inserted in the socket. Lugs 5 are preferably provided for holding the spring in place on the fastener.

I in snap fasteners it is especially adva11- tageous that the spring shall. take up very little space on a face of the article, i. 0., it is desired that the spring shall lie flat upon the device.

The springs are preferably cut from thin sheet metal, and are preferably of a width, somewhat greater than the thickness of the metal. A much stifi'er spring, in proporing a flat face is of especial advantage. The

flat parts of the spring provide a greater contact surface for the goods than would be the case for wire springs.

The inventive idea may receive other expressions than those illustrated and specifically referred to.

V hat is claimed is 2-- l. A snap fastener having prongs adapted to be bent down upon theback of the fastener, a socket having slots therein and a spring of flat sheet material having portions adapted to project through said slots.

2. A snap fastener having elongated prongs adapted to be bent down and overlap laterally upon the back of the fastener, a socket having slots therein and a spring of flat sheet material having portions adapted to project through said slots.

3. Asnap fastener having fiat elongated prongs adapted to be bent down and over lap laterally upon the back of the fastener, a socket having slots therein and a spring of flat sheet material having portions adaptedto project through said slots.

In witness whereof, I have hereunto signed. my name in the presence of two subscribing witnesses.
